WEFT -REPLENISHING MECHANISM FOR LOOMS- SPEGIFIGATICN forming part of Letters Patent No. 754,560, dated March 15, 1904. Application filed October'13, 1902. Serial N9. 127,143. (No model.)

To all whom it may concern:

Be'it known that we,WILI;IAM HENRY HACK- ]NG and HENRY HAWORTH HACKING, subjects of the King of Great Britain and Ireland, and residents of California Iron Works, Bury, county of Lancaster, England, have invented certain new and useful Weft-Replenishing Mechanism for Looms, (for which we have filed application for British Patent No. 7, 890, dated April 4:, A. D. 1902;) and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains' to make and use the same.

This invention relates to an improved construction of the shuttle-changing mechanism described in the specification of Bernard Crossleys United States Patent No.'667 ,7 67 of February 12, 1901, to which reference is made for all features not herein particularly described. In such shuttle-changing mechanism a relay of spare shuttles is contained in a hopper, from the bottom of which they are transported one by one by means of lifter-arms operated by the slay-sword. As the new shuttle rises into the weaving position it pushes upward the used shuttle, which is discharged into are-- ceiver on the next beat up of the slay. Grenerally the principle of operation of the shuttle motion as a whole remains the same as described in the specificationofthe said patent; but the improvements constituting the present invention have for their object to render the operation more perfect and to prevent breakages which are liable to arise in the event of intervening obstacles preventing the movement of the constituent parts of the apparatus.

In the drawings, Figure l is a side elevation of so much of a loom as is necessary to'show the entire invention in an elfective operative combination. the interlocking-lever carrier for the catch 6 Fig. 3 is a detail elevation of theinterlockihglever device and camfor. operating .the shuttle-carrier. Fig. 3 is an elevation, partly in section, of the interlocking arrangement of the two levers it it of Fig. 3. Figs. 4 and 5 Fig. 2 is a. detail elevation of are elevations, partly in section, of the shuttle-carrier.

which brings the shuttle-changing device into operation in the event of a shuttle becoming empty or the weft breaking. A bell-crank lever g is fulcrumed on the slay-sword s and carries a catch 6 on its upper arm 9, this catch having the'same function as the one described in the said patent. The lower arm g of said lever carries a bolt 9, the point of which normally takes into a notch or conical recess in a lug g secured to the slay-sword s. A spring g secured at one end to the bolt and at the other end to the arm 9, normally preserves the engagement of the bolt, and under ordinary conditions the bell-crank lever g behaves as though integral with the slay-sword. Should, however, the catch 6 meet with re sistance while the slay is advancing,;the spring 9 expands and allows the bolt .g to escape from the lug g so that during the continued advance of the slay (to the left in Figs. 1 and 2) the bell-crank lever g simply turns on its fulcrum g and breakage is prevented The arm g carries a spur g, which rising as the lever g turns on its fulcrum and meeting the ordinary stop-rod g ofthe loom displaces thelatter and stops the loom. When the-resistance is removed and the loom restarted, the arm 9 is automatically pulled down by the spring 9 This latter is secured at its upper end to the arm and at its lower end. to a v bracket g on the slay-sword. When this occurs, the spring pulls the bolt into reengagement with its notchin the lug 9 We employ for operating the shuttle-car.- rier two parallel levers h h, fulcrumed at k on a common pin on the loom-frame. Norinstance the one nearest the loomdrame-is formed as an L-lever and carries onthe arm 72. a bowl it, operated when required by an eccentric it toward which it is pulled by the This'improvement relates to the mechanism mally these two leversaot as a single lever adjustable spring k attached at one end to a at one end to the loom-frame. The free end of the strut h takes against and over a pin'fh, carried by a lug h, extending from the lever h. The strut h is connected by a connectingrod h, Fig. 1, to the lifter-arms, so that when the latter begin to move forward for the purpose of changing shuttles the strut h is lifted" clear of the pin h. This enables the spring h to bring the bowl h within range of the action of the eccentric h. The latter in its revolution operates the lever h, and with it the lever h, to slide the shuttle-carrier for the purpose of bringing another shuttle from the 3 hopper. Should the shuttle-carrier meet with I-any obstacle in its course, the resistance will cause the bolt [L3 to disengage itself from the notch 71, whereupon the lever h is freed from the operation of the eccentric lb and breakage of the parts is prevented.

A spring h- 'n compression under a collar on the connecting-rod h bears on the strut -h with suflicient force to prevent it becom- "ing displaced by the shaking or jar of the machinery.

The reserve shuttlesare contained in a hopper "open at its lower end, where the bottom shuttle rests on the slide-bars on which the shuttle slides. The shuttle-carrier is made in two parts; the fore part being hinged and op- 1 'erating as a-spring-controlled latch which on "striking the side of the shuttle is depressed and passing under the shuttle springs up on the other side, so as to embrace the shuttle between the two-parts of the carrier.

i According to-the present invention (refer- --ring more particularlyto Figs. 4 and 5) the *hopper D is normally closed by a slide-block Mn,-adapted to slide on a pair of parallel bars,

one of which'(marked 0Z is shown inFigs. 4

and 5. Normallythe slide-block m lies immediately under the hopper, andthe column of reserve shuttles p rests directly on it. The slide-block is held in position by the spring in, and a stop-pin m The shuttle-carrier, referred to as a whole as E, which is attached at m to the slide-rod 0, operated by the lever "it, (see Fig.- 1,) is constructed of two horizontally-separably components m m, both adapted 'to slide on thesaid' parallel bars and normally drawn together by a spring m When the lever 7b is operated by the eccentric=h so as to move the empty carrier E towardthe hopper D, the two parts m and m of the carrier E move together during the greater part of the stroke. On reaching the hopper the upper edge m of the part on takes against and under the part m of the slideblock m. The further continued movement of the carrier E displaces the slide-block m until the projecting edge m has passed beyond the edge of the lowermost shuttle. Just before it reaches the hopper the rear part m of the shuttle-carrier is restrained by a pin m The part m still travels a short distance, opening the spring m and thus providing a clearance for the drop of the shuttle from the hopper into the carrier. When the part m leaves thepinm on the back stroke of the *lever h, the two parts of the shuttlecarrier come together and safely hold the shuttle until it reaches the shuttle-box, into which it is elevated by the lifter-arms.

In consequence of theconstruction above described the side of'the shuttle is not liable to be injured by the depressible latch 6', Figs. 4 and 5, and the action of transferring the shuttle from the hopper to the carrier is effected in a more gentle manner.

What we claim-as our invention, and desire to secure by Letters Patent, is

1. In a loom for weaving having ashuttlebox on the loom-slay adapted to receive-shuttles through the bottom thereof and a hopper whence reserve shuttles descend and lifting devices for elevating the shuttles, the combination of the slide-block m, the reciprocating longitudinally-divisible shuttle-carrier E, the slide-rod 0, the normally simultaneously acting levers h h adapted to disengagewhen meeting with a resistance, the strut h and the eccentric k for transferring shuttles-from the hopper to underneath the shuttle-box substantially as set forth and shown.

2. In a loom for weaving having a shuttlebox in the loom-slay adapted to receive shuttles through the bottom thereof and means for elevating the shuttles from a reciprocating shuttle-carrier into the shuttle-box, the combination with the slay-sword and the said shuttle-carrier, of the bell-crank lever 9, having its fulcrum on the slay, a spring-operated .locking-bolt gadapted to disengage on the arm 9 of the bell-crank lever meeting with resistance, and a spur g on the other arm 9 ofsaid bell-crank lever adapted to strike the: stoprod when the lever g turns on its fulcrum, substantially as and for the purpose setforth and shown.

In witness whereof we have hereunto set our hands in presence of two witnesses.
